Added forwardingTarget method to be used as a fallback

[zulkis]

Used standard forwarding method forwardingTargetForSelector: from NSObject in order to forward unrecognized messages first directly to the original delegate.

Opened as an output from
pixeldock/RxAppState#11

Interesting that tests are failing with such a changes...

Hi @zulkis ,

we already have forwarding implemented.

-(void)forwardInvocation:(NSInvocation *)anInvocation {
    BOOL isVoid = RX_is_method_signature_void(anInvocation.methodSignature);
    NSArray *arguments = nil;
    if (isVoid) {
        arguments = RX_extract_arguments(anInvocation);
        [self _sentMessage:anInvocation.selector withArguments:arguments];
    }
    
    if (self._forwardToDelegate && [self._forwardToDelegate respondsToSelector:anInvocation.selector]) {
        [anInvocation invokeWithTarget:self._forwardToDelegate];
    }

    if (isVoid) {
        [self _methodInvoked:anInvocation.selector withArguments:arguments];
    }
}

so I'm not sure why did you make that change.

Could you maybe provide a short example that demonstrates what issue are you trying to fix and how does this fix it?

I'm closing this for the time being. I agree with @kzaher this is a bit of a strange addition given we already provide forwarding capabilities. That added with no reply for over 2 years feels like a good time to close this. Thank you!
